Second rateProblem 181 — Time doesn’t always fly when you’re having fun, as this month’s problem by Gregory Smith of Oak Ridge, Tenn., demonstrates.

Deep in the computer room of the prestigious Baath Brokerage House two people were sitting in front of a computer terminal. It was 2:00 a.m., and the cleaning people had gone home. The building was deserted except for the computer room.

“I’ve timed it right down to the second,” calmly replied programmer Betty McBean. “You know the great analog clock in the main trading room? Shortly after 1:00 p.m. tomorrow, the hour hand and minute hand will line up just as they do at 12:00 noon. The very second that happens, this program will automatically sell all the Hulla Ballou stock, based on your tip from Morton Pettifogg.”

“Bless the man!” cried Baath, “What are friends for?”

“There is a complication, however,” continued McBean. “As you know data from the trading terminals is downloaded to the central computer every 15 sec during working hours. Naturally we don’t want this transaction on the records! I’ve calculated the exact time that the hands on the clock line up to be 1:05:35. The next downloading will occur at 1:05:45, so we have 10 sec to delete the information after the sell.”

“Splendid!”

Is 1:05:35 the correct time? Compute where the second hand will be when the hour and minute hands line up to see if Baath and McBean will be setting up future operations in the local penitentiary? Send your answer to:

Take one coin out of Bag #1, two coins out of Bag #2, and three coins out of Bag #3. If the scale reads 6.1 oz, Bag #1 has the fake coins. If it reads 6.2 oz, then Bag #2 has the fake coins. If the reading is 6.3 oz, the the fake coins are in Bag #3.
